Product details
Overview
MAX301CSE+ from Maxim Integrated is a precision dual SPST analog switch IC designed for high-fidelity signal routing in precision instrumentation and test systems. It features 35Ω maximum on-resistance, <2Ω channel-to-channel matching, 15pC charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V bipolar or +10V to +30V single supply.
For engineers reviewing the MAX301CSE+ datasheet, MAX301CSE+ pinout, MAX301CSE+ application, or MAX301CSE+ equivalent, key selection criteria include guaranteed on-resistance flatness (Δ3Ω max), sub-100ns turn-off time, low +85°C off-leakage (<6nA), and SO-16 package compatibility with automated PCB assembly.
Technical Context
The MAX301CSE+ implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process, enabling precise matching and low distortion. Its CMOS/TTL-compatible logic inputs (VL = +5V) interface directly with microcontrollers while maintaining low input loading.
It supports true rail-to-rail analog signal switching across V− to V+, with breakdown voltage up to 44V and guaranteed performance over 0°C to +70°C. Charge injection (15pC typ) and off-isolation (72dB at 1MHz) are specified and tested per channel under defined load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 35Ω - ensures minimal signal attenuation and gain error in precision gain-setting or multiplexing paths |
| On-Resistance Match | <2Ω - enables accurate differential signal switching and matched channel performance in instrumentation front-ends |
| Charge Injection | 15pC - limits voltage glitch on sample-hold capacitors, critical for 12-bit+ data acquisition accuracy |
| Turn-Off Time | <100ns - supports high-speed multiplexing in automated test equipment and real-time signal routing |
| Off-Leakage (85°C) | <6nA - preserves DC integrity in high-impedance sensor interfaces and long-integration-time measurement circuits |
| Analog Signal Range | V− to V+ - allows full-range signal switching without level-shifting, e.g., ±15V op-amp outputs |
| Supply Range | ±4.5V to ±20V or +10V to +30V - provides flexibility in mixed-signal system power architecture design |
Pinout & Package
MAX301CSE+ is housed in a 16-pin narrow SOIC (S16-2) package, RoHS-compliant and lead-free. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Switch output/common terminals - connect to load or downstream signal path; must remain within V− to V+ range |
| 9, 16 | NO1, NO2 | Normally-open analog inputs - conduct only when corresponding INx = logic high; rated for ±30mA continuous |
| 10, 15 | IN2, IN1 | Digital control inputs - TTL/CMOS compatible with VL = +5V; inverted logic sense per internal architecture |
| 11 | V+ | Positive supply - connects to substrate; must be powered before VL/V− to prevent latch-up |
| 12 | VL | Logic supply - fixed at +5V for TTL compatibility; deviation requires CMOS-level validation |
| 13 | GND | Ground reference - serves as negative supply return in single-supply mode; not isolated |
| 14 | V− | Negative supply - establishes lower analog rail; clamped internally to avoid forward-biasing protection diodes |
| 2–7 | N.C. | No internal connection - must remain unconnected; no pull-up/down or routing required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from V− to V+ without clipping - eliminates external level shifters in ±15V systems |
| Guaranteed on-resistance flatness | Δ3Ω max over full signal range - maintains linearity in precision attenuator or programmable-gain amplifier designs |
| Low temperature coefficient | 0.5%/°C typical - minimizes drift-induced gain error across industrial temperature range |
| Bipolar or single-supply operation | Configurable via V+/V−/VL pins - simplifies power domain partitioning in mixed-signal PCB layouts |
| High off-isolation | 72dB at 1MHz - suppresses crosstalk between adjacent channels in dense multiplexer arrays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (1.3Ω typ), wider supply (±15V only), smaller 16-TSSOP package | Lower on-resistance but narrower analog range (±15V vs. ±20V); higher cost | Select ADG1419BRUZ only if ultra-low RON dominates over supply flexibility and temperature range. |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V), 0.9Ω RON, 10-pin VSSOP, no bipolar support | Not suitable for ±15V systems; limited to low-voltage portable electronics | TS5A23157DGSR is viable only in battery-powered, single-rail designs where rail-to-rail analog swing is unnecessary. |
Compared with MAX301CSE+, ADG1419BRUZ offers lower on-resistance but sacrifices bipolar supply flexibility and extended temperature capability, while TS5A23157DGSR lacks rail-to-rail analog handling entirely-making MAX301CSE+ the sole choice for precision ±15V instrumentation-grade switching.

FAQ
What is the maximum allowable analog signal voltage range for MAX301CSE+?
The MAX301CSE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of V+ ≤ 44V above V−. For ±15V supplies, this means analog signals can swing fully from −15V to +15V without clipping or damage, provided proper power sequencing is observed. This capability is confirmed in the Electrical Characteristics table and Typical Operating Characteristics graphs (MAX301-1 through MAX301-4).
Does MAX301CSE+ require a separate logic supply voltage?
Yes, MAX301CSE+ requires VL = +5V for TTL-compatible logic inputs. The VL pin must be tied to a clean +5V source independent of V+ or V−. If VL is connected to V+ or another voltage, the device reverts to CMOS-level input thresholds - which alters noise margins and may affect timing. This requirement is explicitly stated in the Applications Information section and verified in the Input-Voltage High/Low specifications.
Can MAX301CSE+ operate from a single +15V supply?
Yes, MAX301CSE+ supports single-supply operation from +10V to +30V. In this configuration, V− is connected to ground (GND), V+ to +15V, and VL to +5V. Analog signals then swing from 0V to +15V. This mode is validated in the Absolute Maximum Ratings and Electrical Characteristics tables, and referenced in the "Operation with Supply Voltages Other than ±15V" subsection.
What is the guaranteed on-resistance match between the two switches in MAX301CSE+?
The MAX301CSE+ guarantees on-resistance matching of ≤2Ω between its two SPST channels at +25°C, and ≤3Ω over the full operating temperature range (0°C to +70°C). This specification is measured under defined conditions (I(NC or NO) = −10mA, VCOM = ±10V) and appears in the Electrical Characteristics table under "On-Resistance Match Between Channels."
Is MAX301CSE+ pin-compatible with other variants like MAX301ESE or MAX301CPE?
Yes, MAX301CSE+, MAX301ESE, and MAX301CPE share identical pinouts and electrical behavior - differing only in temperature grade (0°C to +70°C for C-grade) and package (narrow SOIC vs. plastic DIP). All three use the same S16-2 or P16-1 footprint and satisfy identical switching, leakage, and resistance specs per the Ordering Information table and Pin Configurations diagrams.
